Working with Metadata

The first thing you need to know about metadata (data about data) in Pixplot is: it's optional. You can create a basic visualization of your pictures with nothing more than a folder full of images called, let's say, "flowers":

pixplot --images "flowers/*.jpg"

Nearly everything about Pixplot will work with just this one command-line argument: zooming and scrolling, seeing one image close-up, and changing layouts. So why would you want to add metadata to the mix? Let's examine a few use cases.

Creating a basic metadata document

First, let's set up the absolute minimum of what we need to use metadata: a CSV (comma-separated values) text file with one column.

filename
flower1.jpg
flower2.jpg

pixplot --images "flowers/*.jpg" --metadata "flower-metadata.csv"

##Adding links to other websites

Let's say you've downloaded your images from a museum website, and you'd like to let uses see their original context. You can do this by adding in a `
